||You can now cast spells reliably without chance of failure, by using rcast (or
adding r flag for mmcast, see help meta-magic).
Drawbacks and limitations:
* Increases mana cost and lag based on failure chance you'd have otherwise.
If your normal success chance is X, cost/lag increase is by factor 1/X.
E.g. reliably casting a spell which normally would have 80% success chance
costs 25% more mana and incurs 25% more lag.
* Cannot be used during combat.
* Does not prevent concentration loss from feeblemind or curse.
